To keep a healthy smile, brushing and flossing your teeth every day should be at the top of your to-do list, along with regular dental visits. Dental visits are usually scheduled every six months when your dental professional will remove any built-up plaque and tartar (hardened plaque deposits) missed during everyday hygiene.

If you've experienced periodontal (gum) disease, however, these dental visits may become even more important toward preventing a re-infection. For one thing, your dentist may want to see you more frequently.

Gum disease is caused by bacteria living in dental plaque, which first infect the superficial layers of gum tissue. Even though the body initiates an inflammatory response to fight it, the infection continues to grow as long as there is plaque present to fuel it. The problem isn't just plaque on the visible tooth surface—hidden plaque beneath the gum line can create deep pockets of infection that can be difficult to treat.

To stop the infection, dentists must manually remove plaque through procedures known as scaling and root planing. Any and all plaque and tartar deposits must be removed, even those deep around the roots, to arrest the infection. This often requires several treatment sessions and sometimes gum surgery to access areas below the gum line.

These types of treatments, especially in the disease's early stages, have a good chance of restoring health to your gums. But because of the high possibility of reinfection, your dentist will need to step up your regular dental maintenance from now on. This could mean visits as frequent as every few weeks, depending on your particular case of gum disease and your dentist's recommendation.

Your dental visits after gum disease may also become more involved than before. Your dentist will now monitor you closely for any signs of reinfection and at the first sign initiate a new round of treatment. You may also need surgical procedures to make some areas around your teeth more accessible for future cleaning and maintenance.

Periodontal maintenance after gum disease helps ensure another infection doesn't rise up to undermine your progress. To paraphrase a well-known quote, eternal vigilance is the price of continuing good dental health.
